    摘要： The present invention provides a color toner for developing an electrostatic image having excellent light transmission for OHP and fixing efficiency, said color toner effectively preventing a low temperature offset and a high temperature offset when it is applied to a fixing device whose coating weight of an oil is reduced. The color toner is characterized in that (i) it comprises a binding resin and a colorant, (ii) its storage elastic modulus at 90° C. (G′90) is not more than 6×104 Pa, (iii) its storage elastic modulus at 140° C. (G′140) is not less than 5×102 Pa, (iv) a temperature showing a maximum value of &dgr; in tan&dgr;=G″/G′ (wherein G′ is a storage elastic modulus of the color toner, and G″ is a loss elastic modulus of the color toner) exists in the range of 90-120° C., and (v) the maximum value of &dgr; is not less than 60°.
